Inspect the roof curb for correct installation. The unit and curb  
assembly should be level. Inspect the flashing of the roof  
mounting curb to the roof, especially at the corners, for good  
workmanship. Also check for leaks around gaskets. Note any  
deficiencies in a separate report and forward to the contrac-  
tor.  
The Startup, Adjustments, and Checks procedure provides a  
step-by-step sequence which, if followed, will assure the  
proper startup of the equipment in the minimum amount of  
time. Air balancing of duct system is not considered part of  
this procedure. However, it is an important phase of any air  
conditioning system startup and should be performed upon  
completion of the Startup, Adjustments, and Checks proce-  
dure. The Startup, Adjustments, and Checks procedure at  
outside ambients below 55°F should be limited to a readi-  
ness check of the refrigeration system with the required final  
check and calibration left to be completed when the outside  
ambient rises above 55°F.  
OBSTRUCTIONS, FAN CLEARANCE AND WIRING  
Remove any extraneous construction and shipping materi-  
als that may be found during this procedure. Rotate all fans  
manually to check for proper clearances and that they rotate  
freely. Check for bolts and screws that may have jarred loose  
during shipment to the job site. Retighten if necessary. Re-  
tighten all electrical connections.  
PRE-STARTUP PRECAUTIONS  
It is important to your safety that the unit has been properly  
grounded during installation. Check ground lug connection  
in main control box for tightness prior to closing circuit breaker  
or disconnect switch. Verify that supply voltage on line side  
of disconnect agrees with voltage on unit identification plate  
and is within the utilization voltage range as indicated in Ap-  
pendix C Electrical Data.

System Voltage - That nominal voltage value assigned to a  
circuit or system for the purpose of designating its voltage  
class.  
Nameplate Voltage - That voltage assigned to a piece of  
equipment for the purpose of designating its voltage class  
and for the purpose of defining the minimum and maximum  
voltage at which the equipment will operate.  
Utilization Voltage - The voltage of the line terminals of the  
equipment at which the equipment must give fully satisfac-  
tory performance. Once it is established that supply voltage  
will be maintained within the utilization range under all sys-  
tem conditions, check and calculate if an unbalanced condi-  
tion exists between phases. Calculate percent voltage un-  
balance as follows:  
t = Span length, inches  
C = Center distance, inches  
D = Larger sheave diameter, inches  
d = Smaller sheave diameter, inches  
h = Deflection height, inches

Verify that all duct connections are tight and that there is no  
air bypass between supply and return.  
RECOMMENDED POUNDS OF FORCE PER BELT  
New V-belts will drop rapidly during the first few hours of use.  
Check tension frequently during the first 24 hours of opera-  
tion. Tension should fall between the minimum and maximum  
force. To determine the deflection distance from a normal  
position, measure the distance from sheave to sheave using  
a straightedge or a cord. This is your reference line. On mul-  
tiple belt drives, an adjacent undeflected belt can be used as  
a reference.  
FILTER SECTION CHECK  
Remove filter section access panels and check that filters  
are properly installed. Note airflow arrows on filter frames.  
BELT DRIVE  
BEARING CHECK  
Prior to energizing any fans, check and make sure that all  
setscrews are tight so that bearings are properly secured to  
shafts.  
EVAPORATOR FAN ROTATION CHECK (THREE PHASE MODELS  
ONLY)  
For heat pump units, the airflow must be adjusted so that the  
air temperature rise falls within the ranges given stated on  
Data Plate (see Appendix A - Blower Performance).  
Check that fan rotates clockwise when viewed from the drive  
side of unit and in accordance with rotation arrow shown on  
blower housing. If it does not, reverse the two incoming power  
cables at Single Point Power Block. In this case, repeat bear-  
ing check.  
NOTE: Section on high static tables may require a field motor  
change.  
Do not attempt to change load side wiring. Internal wiring  
assures all motors and compressors will rotate in correct di-  
rection once evaporator fan motor rotation check has been  
made.  
TENSION AND ALIGNMENT ADJUSTMENT  
Correct belt tension is very important to the life of your belt.  
Too loose a belt will shorten its life; too tight, premature mo-  
tor and bearing failure will occur. Check you belt drive for  
adequate “run-in” belt tension by measuring the force required  
to deflect the belt at the midpoint of the span length. Belt  
tension force can be measured using a belt tension gauge,  
available through most belt drive manufacturers.  
ELECTRICAL INPUT CHECK  
Make preliminary check of evaporator fan ampere draw and  
verify that motor nameplate amps are not exceeded. A final  
check of amp draw should be made upon completion of air  
balancing of the duct system (see Appendix C).  
12  
11. Check for air leaks in the ductwork.See Sections on  
Air Flow Adjustments.  
REFRIGERATION SYSTEM CHECKS  
Ensure the hold-down bolts on the compressor are secure  
and have not vibrated loose during shipment. Check that vi-  
bration grommets have been installed. Visually check all pip-  
ing and clamps. The entire refrigeration system has been  
factory charged and tested, making it unnecessary to field  
charge. Factory charges are shown in Appendix C and on  
the unit nameplate.  
12. Make sure the unit is free of “rattles”, and the tubing  
in the unit is free from excessive vibration. Also make  
sure tubes or lines are not rubbing against each other  
or sheet metal surfaces or edges. If so, correct the  
trouble.  
13. Set the thermostat at the appropriate setting for  
cooling and heating or automatic change over for  
normal use.  
Install service manifold hoses. Gauges should read satura-  
tion pressure corresponding to ambient temperature. Charge  
should be checked to obtain 12° to 15° of sub-cooling per  
system (i.e. compressor circuits).  
14. Be sure the Owner is instructed on the unit operation,  
filter, servicing, correct thermostat operation, etc.  
REFRIGERATION PERFORMANCE CHECK  
START-UP PROCEDURE AND CHECKLIST  
Under normal summertime (full load) operating conditions,  
superheat should be between 8°F and 12°F and sub-cooling  
measured at the condenser outlet should be 15°F (nominal).  
A 25°F to 35°F temperature difference should exist between  
the entering condenser air and the temperature correspond-  
ing to the compressor saturated discharge pressure. Check  
that compressor RLA corresponds to values shown in Ap-  
pendix C. RLA draw can be much lower than values listed at  
low load conditions and low ambient condensing tempera-  
tures. Values in Appendix C can slightly exceed at high load  
conditions and high ambient condensing temperatures.  
Begin with power turned off at all disconnects.  
1. Turn thermostat system switch to “Cool,” and fan  
switch to “Auto” and turn temperature setting as high  
as it will go.  
2. Inspect all registers and set them to the normal open  
position.  
3. Turn on the electrical supply at the disconnect.  
4. Turn the fan switch to the “ON” position. The blower  
should operate after a 7-second delay.  
AIR FLOW ADJUSTMENTS  
5. Turn the fan switch to “Auto” position. The blower  
should stop after a 65 second delay.  
The drive on the supply fan is typically set in the middle of the  
RPM range. The drive motor sheave pitch diameter is field  
adjustable for the required airflow. Refer to “Drive  
Adjustments” section below.  
6. Slowly lower the cooling temperature until first stage  
COOL (LOW COOL) starts. The blower, both fans,  
and first stage compressor should now be operating.  
Allow the unit to run 10 minutes, make sure cool air is  
being supplied by the unit.  
When the final adjustments are complete, the current draw  
of the motor should be checked and compared to the full  
load current rating of the motor. The amperage must not ex-  
ceed the service factor stamped on the motor nameplate.  
The total airflow must not be less than that required for op-  
eration of the electric heaters or the furnace.  
7. Lower the cooling temperature further until second  
stage COOL (HIGH COOL) starts. The blower, both  
fans, and both compressors should now be operating.  
Allow the unit to run 10 minutes, make sure cool air is  
being supplied by the unit.  
If an economizer is installed, check the unit operating bal-  
ance with the economizer at full outside air and at minimum  
outside air. Upon completion of the air flow balancing, we  
recommend replacing the variable pitched motor sheave with  
a properly-sized fixed sheave. A matching fixed sheave will  
provide longer belt and bearing life and vibration free opera-  
tion. Initially, it is best to have a variable pitched motor sheave  
for the purpose of airflow balancing, but once the balance  
has been achieved, fixed sheaves maintain alignment and  
minimize vibration more effectively. For direct drive units, move  
green wire for fan.  
8. Turn the temperature setting to the highest position,  
stopping the unit. The indoor blower will continue to  
run for 65 seconds.  
9. Turn the thermostat system switch to “OFF” and  
disconnect all power when servicing the unit.

FINAL SYSTEM CHECKS  
10. Check to see if all supply and return air grilles are  
adjusted and the air distribution system is balanced  
for the best compromise between heating and cooling.

MOTOR SHEAVE ADJUSTMENTS  
CAUTION  
VL, VM & 2VP VARIABLE PITCH KEY TYPE MOTOR SHEAVES  
SHEET METAL PARTS, SCREWS, CLIPS AND SIMILAR ITEMS INHERENTLY  
HAVE SHARP EDGES, AND IT IS NECESSARY THAT THE INSTALLER AND  
SERVICE PERSONNEL EXERCISE CAUTION.  
The driving and driven motor sheaves should be in align-  
ment with each other and the shafts parallel.  
Your Self Contained PackagedAir Conditioner and Heat Pump  
should operate for many years without excessive service calls  
if the unit is installed properly. However it is recommended  
that the homeowner inspect the unit before a seasonal start  
up. The coils should be free of debris so adequate airflow is  
achieved. The return and supply registers should be free of  
any obstructions. The filters should be cleaned or replaced.  
These few steps will help to keep the product up time to a  
maximum. The Service section that follows should help in  
identifying problems if the unit does not operate properly.  
VL & VM SHEAVES ADJUSTMENT  
1. Loosen set screw “B” using a 5/32" Allen key.  
2. Making half or full turns from closed position, adjust  
sheave pitch diameter for desired speed. DO NOT  
OPEN MORE THAN SIX FULL TURNS.  
3. Tighten set screw “B” securely over flat.  
4. Carefully put on belts and adjust belt tension. DO NOT  
FORCE BELTS OVER GROOVES.  
5. Ensure all keys are in place and the set screws tight  
before starting drive. Recheck set screws and belt  
tension after 24 hours service.  
FILTERS  
NOTE: Future adjustments should be made by loosening the  
belt tension and increasing or decreasing the pitch diameter  
of the sheave by half or full turns as required. Readjust belt  
tension before starting drive.  
CAUTION  
TO PREVENT PROPERTY DAMAGE DUE TO FIRE AND LOSS OF  
EQUIPMENT EFFICIENCY OR EQUIPMENT DAMAGE DUE TO DUST AND LINT  
BUILD UP ON INTERNAL PARTS, NEVER OPERATE UNIT WITHOUT AN AIR  
FILTER INSTALLED IN THE RETURN AIR SYSTEM.  
Every application may require a different frequency of replace-  
ment of dirty filters. Filters must be replaced at least every  
three (3) months during operating seasons.  
C
Dirty filters are the most common cause of inadequate heat-  
ing or cooling performance. Filter inspection should be made  
at least every two months; more often if necessary because  
of local conditions and usage.  
B
VL & VM  
Dirty throwaway filters should be discarded and replaced with  
a new, clean filter.  
NOTE: Do not operate sheave with flange projecting beyond  
the hub end.  
Disposable return air filters are supplied with this unit. See  
the unit Specification Sheet or Technical Manual for the cor-  
rect size and part number. To remove the filters, remove the  
filter access panel on return side of the unit.

annually and cleaned as frequently as necessary to keep the pump installation. Do not allow air entering the indoor coil to  
finned areas free of lint, hair and debris.  
drop below 65° F. Air below this temperature will cause low  
discharge pressure, thus low suction pressure, and exces-  
sive defrost cycling resulting in low heating output. It may  
also cause false defrosting.  
CONDENSER, EVAPORATOR, AND INDUCED DRAFT MOTORS  
Bearings on the air circulating blower motor, condenser mo-  
tor and the combustion fan motor are permanently lubricated.  
No additional oiling is required.  
UNDERCHARGE  
An undercharged heat pump on the heating cycle will cause  
low discharge pressure resulting in low suction pressure and  
frost accumulation on the outdoor coil.  
LUBRICATION  
The fan shaft bearings, the 1 to 2 HP supply fan motors the  
condenser fan motors and compressors are permanently lu-  
bricated.  
POOR “TERMINATING” SENSOR CONTACT  
The unit’s defrost terminating sensor must make good ther-  
mal contact with the outdoor coil tubing. Poor contact may  
not terminate the unit’s defrost cycle quickly enough to pre-  
vent the unit from cutting out on high discharge pressure.
